Biomedical Data Analyst

Computercraft is seeking a Biomedical Data Analyst to support the National Library of Medicine (NLM) at the National Institutes of Health in Bethesda, Maryland. NLM is the world’s largest biomedical and health research library and maintains a preeminent collection of biomedical literature and information resources. To make biomedical and life sciences literature accessible, NLM maintains PubMed (a publicly accessible search engine), which includes MEDLINE, a bibliographic database with more than 31 million references. MeSH (Medical Subject Headings), a distinctive feature of MEDLINE, is NLM’s controlled vocabulary thesaurus that gives uniformity and consistency to the references.

In this role, you will work full-time providing data analysis and computational support for data-driven efforts to evaluate and improve the MEDLINE indexing product. Working under the technical direction and oversight of the Senior Biomedical Data Analyst and within established analytical approaches, you will support the processing, preparation, validation, and analysis of datasets, including PubMed web search and API user log data, used to evaluate MeSH vocabulary and automated MeSH indexing algorithm performance. You will assist with analyses of indexing performance and user search behavior and contribute to the development of data products, reports, and other analytical outputs used to inform improvements to MEDLINE indexing.

Work performed by the Biomedical Data Analyst is subject to technical review and quality assurance by the Senior Biomedical Data Analyst. The Biomedical Data Analyst shall incorporate feedback, make necessary corrections, and maintain analytical code, documentation, and work products in accordance with established methodologies, technical standards, and quality requirements.
